22⋅102=c2
Rewrite the equation as c2=22⋅102.
c2=22⋅102
Take the square root of both sides of the equation to eliminate the exponent on the left side.
c=±22⋅102
Simplify the right side of the equation.
Raise 2 to the power of 2.
c=±4⋅102
Raise 10 to the power of 2.
c=±4⋅100
Multiply 4 by 100.
c=±400
Rewrite 400 as 202.
c=±202
Pull terms out from under the radical, assuming positive real numbers.
c=±20
c=±20
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the ± to find the first solution.
c=20
Next, use the negative value of the ± to find the second solution.
c=-20
The complete solution is the result of both the positive and negative portions of the solution.
c=20,-20
c=20,-20
c=20,-20
Solve for c 2^2*10^2=c^2
